Deaths caused by systemic mycoses such as paracoccidioidomycosis, cryptococcosis, histoplasmosis, candidiasis, aspergillosis, coccidioidomycosis and zygomycosis amounted to 3,583 between 1996-2006 in Brazil. When analysed as the underlying cause of death, paracoccidioidomycosis represented the most important cause of deaths among systemic mycoses (~ 51.2%). When considering AIDS as the underlying cause of death and the systemic mycoses as associated conditions, cryptococcosis (50.9%) appeared at the top of the list, followed by candidiasis (30.2%), histoplasmosis (10.1%) and others. This mortality analysis is useful in understanding the real situation of systemic mycoses in Brazil, since there is no mandatory notification of patients diagnosed with systemic mycoses in the official health system.

Chronic hepatitis C is often a progressive, fibrotic disease that can lead to cirrhosis and other complications. The recommended therapy is a combination of interferon and ribavirin. Besides its antiviral action, interferon is considered to have antifibrotic activity. We examined the outcome of hepatic fibrosis and inflammation in chronic hepatitis C patients who were non-responders to interferon. We made a case series, retrospective study, based on revision of medical records and reassessment of liver biopsies. For inclusion, patients should have been treated with interferon alone or combined with ribavirin, with no virological response (non responders and relapsers) and had a liver biopsy before and after treatment. Histological evaluation included: i-outcome of fibrosis and necroinflammation; ii-annual fibrosis progression rate evaluation, before and after treatment. Seventy-five patients were included. Fifty-seven patients (76%) did not show progression of fibrosis after treatment, compared to six (8%) before treatment (p < 0.001). The mean annual fibrosis progression rate was significantly reduced after treatment (p = 0.036). Inflammatory activity improved in 19 patients (25.3%). The results support the hypothesis of an antifibrotic effect of interferon-based therapy, in non-responder patients. There was evidence of anti-inflammatory effects of treatment in some patients.

OBJETIVO: Analisar as características das quedas no grupo etário com 60 anos ou mais, com ênfase nas quedas no mesmo nível, residentes no Estado de São Paulo, a partir da análise das diferentes fontes de informação oficiais. MÉTODOS: Foram analisadas as 1.328 mortes registradas no SIM em 2007, 20.726 internações no SIH/SUS em 2008 e os 359 atendimentos realizados em 24 UEs do Estado de São Paulo em 2007. Um teste de regressão logística foi utilizado para testar associações entre variáveis nos atendimentos em emergências. RESULTADOS: O sexo masculino preponderou nas mortes (51,2 %) enquanto o sexo feminino preponderou nas internações (61,1%) e atendimentos em emergências (60,4%). O coeficiente de mortalidade foi 31/100.000 habitantes, aumentando com a idade e atingindo o valor de 110,7/100.000 habitantes na faixa de 80 anos e mais. As quedas no mesmo nível foram responsáveis pela maior proporção de mortes definidas (35%), nas internações (47,5%) e também nas emergências (66%), crescendo de importância com o aumento das faixas etárias. A residência foi o local de ocorrência em 65,8% dos casos atendidos nas emergências. Os traumatismos de cabeça assumem importância nas mortes; as fraturas de fêmur foram as lesões mais frequentes nas internações e emergências. Nas emergências, as mulheres foram 1,55 vezes significativamente mais prováveis de serem atendidas por uma queda do que pelas outras causas externas que os homens. Comparativamente à faixa de 60 a 69 anos, os indivíduos na faixa de 70 a 79 anos foram 2,10 vezes e os indivíduos de 80 anos e mais foram 2,26 vezes significativamente mais prováveis de serem atendidos por uma queda do que pelas outras causas externas. Não houve diferença estatisticamente significante quanto ao sexo ou faixa etária quando se comparou os indivíduos que sofreram quedas no mesmo nível e outros tipos de queda. CONCLUSÃO: Recomenda-se que a prevenção das quedas entre idosos entre na pauta de discussão das políticas públicas sem mais demora.

OBJETIVO: Determinar a prevalência, distribuição etária, sazonalidade, características clínicas da doença Lyme-símile em menores de 15 anos. MÉTODOS: De julho/1998 a dezembro/2000 foi conduzido um estudo transversal em 333 pacientes, com exantema e febre. Foram coletadas amostras pareadas de sangue para a identificação de patógenos. Somente em 193 amostras, negativas aos outros patógenos (Parvovirus B19, Herpesvírus 6 humano, Sarampo, Rubéola, Dengue, Escarlatina e Enterovírus), foram realizadas a pesquisa da borreliose pelos métodos de Enzyme-Linked Immunosorbent Assay e Western-blotting. Outras variáveis clínicas, socioeconômicas, demográficas e climáticas foram estudadas. RESULTADOS: A prevalência da doença foi de 6,2%(12/193). Das variáveis estudadas, houve predomínio em <6anos(83,2%); sexo feminino (66,7%); procedência da cidade de Franco da Rocha (58,3%); com sazonalidade no outono-verão. O intervalo de atendimento foi de quatro dias. Sinais e sintomas com significância estatística: prurido, ausência da fissura labial e bom estado clínico. Outros dados presentes foram: irritabilidade (80%); febre (?38ºC) (58,3%) com duração de um a três dias. O exantema foi do tipo máculo-papular (33,3%), urticariforme (25%) e escarlatiniforme (16,7%); predominando em tronco (60%). Não houve apresentação clínica característica para diagnóstico da doença de Lyme-símile nestes pacientes. A sensibilidade e especificidade para o diagnóstico clínico contraposta com o diagnóstico laboratorial foi zero. O acompanhamento de 10 casos durante dois anos não evidenciou complicações cardiológicas ou neurológicas. Este é o primeiro estudo desta doença em crianças brasileiras. CONCLUSÃO: A prevalência da doença Lyme-símile foi baixa, não tendo sido lembrada no diagnóstico inicial dos exantemas, mas seu conhecimento é necessário, necessitando maior atenção médica.

This study assessed oral health outcomes (perceived dental treatment need, untreated dental caries, gingival bleeding, periodontal pockets, and pain in teeth and gums), in relation to color/race inequalities among adolescents in each Brazilian region. The database included dental examination and interview of 16,833 15-19-year-old adolescents, surveyed by the Brazilian health authority, from May 2002 to October 2003, in accordance with international diagnostic criteria standardized by the World Health Organization. Prevalence ratios estimated by Poisson regression, and controlled by socioeconomic status and access to fluoridated piped water, assessed oral health differentials among color/race groups and country's regions. Except for periodontal pockets, prevalence figures were higher in the North and Northeast: perceived dental treatment needs, untreated dental caries, gingival bleeding at probing and pain in teeth and gums varied between 80-83%, 75-76%, 38-43%, and 17-18%, respectively, in these regions. Adolescents living in the Southeast - the richest Brazilian region - presented a better general profile of oral health than their counterparts living in the remaining regions; they had a lower prevalence of untreated dental caries (54%) and unfavorable gingival status (29%). However, the Southeast presented color/race inequalities in all oral health outcomes, with a poorer profile systematically affecting browns or blacks, depending on the oral health condition under consideration. These results reinforce the need for expanding the amplitude of health initiatives aimed at adolescent oral health. Socially appropriate health programs should concurrently aim at the reduction of levels of oral disease and its inequalities.

The aim of this study was to validate the intake of carotenoids, fruits and vegetables estimated by the Food Frequency Questionnaire for Adolescents (FFQA) using the method of triads. Blood samples were collected from 80 elementary school adolescents to assess serum levels of β-carotene. Partial correlation coefficients (r) were calculated between an estimated intake of carotenoids, fruits and vegetables and the serum levels of β-carotene. Validity coefficients were calculated using the method of triads. With the exception of carotenoids, partial r from the food frequency questionnaire (FFQ) were greater than those of the 24-hour recall (24hR). The fruit/vegetable group showed the highest partial r for the FFQ (r = 0.235) and the 24hR (r = 0.137). The highest validity coefficient was obtained for the vegetable group, as assessed by the FFQ (r = 0.873). On average, the validity coefficient values for the FFQ were greater than those obtained for the 24hR or the β-carotene serum levels. The FFQA is an accurate tool for estimating the intake of carotenoids, fruits and vegetables in this population group.

OBJETIVO: Identificar o tamanho das porções dos alimentos e das preparações mais consumidas ou que mais contribuem com o valor energético total da dieta de adultos e idosos. MÉTODOS: Realizou-se inquérito domiciliar de base populacional em 2003, com amostra representativa de 1 477 indivíduos acima de 20 anos residentes no município de São Paulo. O consumo alimentar foi verificado pelo recordatório de 24 horas, digitado no programa Nutrition Data System. Os alimentos e as preparações selecionados para averiguação da porção foram os consumidos por, no mínimo, 10% da população de estudo ou que contribuíram com até 80% do valor energético total. As porções médias, obtidas pelo percentil 50, foram comparadas segundo sexo e estado nutricional, por meio do teste de Kruskal Wallis. RESULTADOS: Arroz e feijão foram os alimentos mais consumidos e que mais contribuíram para o valor energético da dieta. Os homens consumiram maior porção destes alimentos, quando são comparados às mulheres. Observou-se que a porção de leite está abaixo do estipulado pelo Guia Alimentar Brasileiro, porém a maior diferença encontrada foi em relação à alface e ao tomate. Verificou-se que indivíduos com excesso de peso consomem maiores porções de peito de frango. CONCLUSÃO: O tamanho das porções de alguns alimentos é maior entre homens, porém, na prática, não há como diferenciar, em medidas caseiras, valores tão próximos como os encontrados na maioria dos alimentos. As porções dos principais alimentos dos grupos de verduras e legumes e leite e derivados são menores que o proposto pelo Guia Alimentar.

This study evaluated the microbiological quality of hamburgers and the microbe community on the hands of vendors in Cuiabá, Mato Grosso, Brazil, in relation to vendors´ awareness as to what constitute acceptable food-handling practices as part of a broad-spectrum research programme on street foods in Brazil . Sale of the hamburger known as the 'baguncinha' is common and widespread in urban Cuiabá, Mato Grosso, Brazil. Food inspectors encounter various difficulties in carrying out inspections. One hundred and five hamburgers samples were evaluated using conventional methods including tests for facultative aerobic and/or anaerobic mesophytic bacteria, coliform counts at 45 °C, the coagulase test for Staphylococcus, Gram-staining for the presence of Bacillus cereus, Clostridium sulphite reductase and Salmonella spp. The hamburgers were categorized as unsuitable for human consumption in 31.4% of samples, with those testing positive for coliforms and Staphylococcus at unacceptably high levels by Brazilian standards. High levels of microbiological contamination were detected on the hands of the food handlers and mesophytic bacterial counts reached 1.8 × 10(4) CFU/hand. Interviews were carried out by means of questionnaires to evaluate levels of awareness as to acceptable food handling practices and it was found that 80,1% of vendors had never participated in any kind of training.

OBJECTIVES: To assess the influence of Nd:YAG (neodymium: yttrium-aluminum- garnet) laser unilateral posterior capsulotomy on visual acuity and patients' perception of difficulties with vision-related activities of daily life. METHODS: We conducted an interventional survey that included 48 patients between 40 and 80 years of age with uni- or bilateral pseudophakia, posterior capsule opacification, and visual acuity <0.30 (logMAR) in one eye who were seen at a Brazilian university hospital. All patients underwent posterior capsulotomy using an Nd:YAG laser. Before and after the intervention, patients were asked to complete a questionnaire that was developed in an exploratory study. RESULTS: Before posterior capsulotomy, the median visual acuity (logMAR) of the included patients was 0.52 (range 0.30-1.60). After posterior capsulotomy, the median visual acuity of the included patients improved to 0.10 (range 0.0-0.52). According to the subjects' perceptions, their ability to perform most of their daily life activities improved after the intervention (p<0.05). CONCLUSIONS: After patients underwent posterior capsulotomy with an Nd:YAG laser, a significant improvement in the visual acuity of the treated eye was observed. Additionally, subjects felt that they experienced less difficulty performing most of their vision-dependent activities of daily living.

PURPOSE: To analyze the usefulness of the weight gain/height gain ratio from birth to two and three years of age as a predictive risk indicator of excess weight at preschool age. METHODS: The weight and height/length of 409 preschool children at daycare centers were measured according to internationally recommended rules. The weight values and body mass indices of the children were transformed into a z-score per the standard method described by the World Health Organization. The Pearson correlation coefficients (rP) and the linear regressions between the anthropometric parameters and the body mass index z-scores of preschool children were statistically analyzed (alpha = 0.05). RESULTS: The mean age of the study population was 3.2 years (± 0.3 years). The prevalence of excess weight was 28.8%, and the prevalence of overweight and obesity was 8.8%. The correlation coefficients between the body mass index z-scores of the preschool children and the birth weights or body mass indices at birth were low (0.09 and 0.10, respectively). There was a high correlation coefficient (rP = 0.79) between the mean monthly gain of weight and the body mass index z-score of preschool children. A higher coefficient (rP = 0.93) was observed between the ratio of the mean weight gain per height gain (g/cm) and the preschool children body mass index z-score. The coefficients and their differences were statistically significant. CONCLUSION: Regardless of weight or length at birth, the mean ratio between the weight gain per g/cm of height growth from birth presented a strong correlation with the body mass index of preschool children. These results suggest that this ratio may be a good indicator of the risk of excess weight and obesity in preschool-aged children.

The green turtle Chelonia mydas feeds and nests in the Brazilian coastal area and is considered an endangered species by the World Conservation Union (IUCN 2009) and threatened by the Red List of Brazilian Fauna (Ministério do Meio Ambiente 2009). Fibropapillomatosis is a disease characterized by benign skin tumors (fibropapillomas), and it is one of the main threats to the survival of this species. Studies suggest the involvement of viruses as infectious agents associated with environmental and genetic factors. Blood samples were collected from 45 turtles captured in the coastal area of the state of Sao Paulo, Brazil. From these, 27 were affected by fibropapillomas and 18 were tumor free. Biometrical data on the turtles, size, location and quantity of tumors were recorded. The area occupied by fibropapillomas per animal was calculated and four groups were determined according to severity of the disease or its absence. The objective of the study was to compare hemogram results of the sea turtles classified in these four groups. The lowest hematocrit value was observed in severely affected animals. In the hemoglobin assay, the highest value was observed in the group of tumor free turtles and the lowest, in animals severely affected. Lymphocyte counts and curved carapace length were on the verge of statistical significance.
